The Batéké plateaux are located around the border between the Republic of Congo and Gabon. In the latter, they are found in the Haut-Ogooué Province, while the Plateaux Province of Congo is named after them. They reach between 550 and 830 metres, and are rich in manganese. The Bateke Plateau is an ancient volcanic area.
Several rivers rises in that area, including the Niari River, which flows in Congo, the Ogooue, Mpassa, Ndjoumou, Lekabi and Lekey Rivers which flow in Gabon.
